Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector having an expansion circuit board.

In recent years, under the vigorous development of the Internet industry, the industry has continuously developed related technologies for high-speed transmission of telecommunication signals, so as to provide a more convenient network environment for the vast network population. So far, the transmission speed of the RJ45 connector has entered the stage of C6A up to 500MHz per second. However, the industry has found that the increase in transmission speed will increase the impact of crosstalk and reduce the transmission quality of the RJ45 connector. As a result, crosstalk will become a stumbling block to the growth of the RJ45 connector.

Since the transmission rate of the current RJ45 connector is much larger than the previous 250 MHz, the previous change in terminal ordering and position has not effectively suppressed crosstalk interference. Therefore, the operator must additionally set up noise suppression components (such as resistors or capacitors) to improve the crosstalk suppression effect. However, the current problem faced by the industry is that the space of the circuit board inside the RJ45 connector is limited, and there is not enough space to set up a circuit that suppresses crosstalk. Therefore, how to quickly and conveniently increase the circuit board setting area in the limited space of the RJ45 connector, so that the operator can additionally set up a circuit that suppresses crosstalk (Crosstalk) to reduce the influence of crosstalk interference will be solved by the industry. One of the problems.

The present invention provides an electrical connector for suppressing magnetic field interference generated by electrical connector signal transmission.
